Windows 10 Enterprise builds on Windows 10 Pro, adding advanced features designed to meet the demands of medium and large sized organizations. It provides advanced capabilities to help protect against the ever-growing range of modern security threats targeted at devices, identities, applications and sensitive company information. Windows 10 Enterprise also supports the broadest range of options for operating system deployment and comprehensive device and app management. It will be available to Volume Licensing customers, so they can take advantage of the latest innovation and security updates on an ongoing basis. At the same time, they will be able to choose the pace at which they adopt new technology, including the option to use the new Windows Update for Business. With Windows 10, Enterprise customers will also have access to the Long Term Servicing Branch as a deployment option for their mission critical devices and environments. And as with prior versions of Windows, Active Software Assurance customers in Volume Licensing can upgrade to Windows 10 Enterprise as part of their existing Software Assurance benefits. (Note: the Windows 10 Enterprise E3 edition includes most of the suite of Windows 10 Enterprise features but it does NOT include Windows Defender Advanced Threat Protection, which is available in the E5 edition.)
